From a Close Minded Audiophile--Sumiko S5 Subwoofer Helps

I thought I've never met a subwoofer that I liked.  Well, I stopped auditioning them when I left home theatre in the 90s and never looked back. 

I hooked up a Sumiko S5 two days ago.  At first I thought it sounded wonky and, while better than subwoofers that I remember, not for me.  I was pretty certain that I would be sending it back.  

I didn't use software to set it up.  I simply experimented with tons of fuzzy logic, real world trial and error.  I found the best setting was at about 45hz on the crossover, and the gain set to about 11/10:30.  The unit is hooked up to my Creek Evolution 100A integrated amplifier via Speakon hookup.  

The results are superb.  You cannot see the subwoofer (it's placed adjacent to my mid century media center on the right wall).  You also cannot hear it--at least there's nothing directional or flubby coming out of it to give its presence away.  I've played guitar for many years and I used my ears to painstakingly tune the unit in to a point where it ever-so-slightly overlaps my floorstanding PSB Imagine T2 loudspeakers bottom end.  The effect is very subtle, yet impressive.  The way I have it set up makes it doing so little;  it's merely rounding off the bass on the PSBs.  This allows drums, stand up bass, and electric bass to sound fuller without ANY of the bad bass that I do not want. 

Let me just say that I listen to 70% vinyl, and about 50% of that is jazz, 20% acoustic/folk, and the remainder rock/pop.  I do not want to hear sounds that do not sound like instruments being played in a studio.  I hate bloated bass.  I only want to hear notes. Well, that's exactly what I have. 

The introduction of the Sumiko has pushed the gestalt of my listening experience to a spot where things are overall better.  The midrange and highs are in no way adversely affected as I have this thing set up.  Indeed, the imaging and realism seems to have opened up in a very nice way. And, I don't have to drive my amp as hard to get the scenario to be believable.  I have much more fun at lower levels than previously. 

I'm curious as to others' thoughts, opinions, comments, experiences. 


Thanks!

What I think Bob is saying is that low frequency distortion is kind of inversely related to driver size. The only way to get clean distortion free, low bass is with lots of surface area.

Few report it or measure it, but fortunately SoundStage does along with compression. You can get a list of all speakers tested here:

Sadly, most hear bad room modes and report that assume it's distortion, when it's not the case, but they assume big woofers must sound terrible.

So, yes, you are an Audiophile heretic for using a subwoofer, but let them not cause you to falter for your cause is righteous.  :)

Best,

Erik

The only upgrade better than a sub is two subs...

Great sounding well designed main speakers functioning full range can yield very musical results, and small woofers (and baffles) can also sound great, with astonishing soundstage capabilities…adding subs makes it all better as good subs can charge a room and really help mains to sing even when the mains are left at the full range they're designed for in the first place. I use 2 RELs with Silverline Prelude mains (3.75" D'Appolito array woofers in each) and the system never displays audible distortion even when driven to levels approaching discomfort. Fear not the full range.
